I've downloaded apache-tomcat-8.0.8 archive, then I've unzipped it and tried to add it in Preferences -> Server -> Runtime Environments by clicking Search and selecting path to the uzipped archive. What I'm getting is Server Error
No new server runtime environments were found.
Any ideas why it might be happening? I have no Apache Tomcat options in New Server Runtime Environment window, which I get by clicking Add in the previous one. There are such options in every tutorial I read.
